Abstract
Nano Zn0.75−xMn x Cd0.25S (x = 0, 0.05. 0.1, 0.15) doped PVA/PEG (7:3) polymer blend was fabricated. X-ray diffraction and scanning electron microscope techniques were used to investigate the possible formed phases in the nanofiller samples, and the formation of the blends. The changes in different optical parameters of PVA/PEG (7:3) upon doping with nano Zn0.75−xMn x Cd0.25S were investigated. The optical bandgap of the polymer blend was decreased from 5.78 to 4.83 eV upon doping with Zn0.75Cd0.25S, and then increased a little by increasing the Mn content (x). The enhancement of nonlinear parameters as the blend doped especially with Zn0.75Cd0.25S nominated this blend to employ in various nonlinear optical and photonic fields. The fluorescence (FL) intensity was decreased as the PVA/PEG (7:3) blend was doped with nano Zn0.75−xMn x Cd0.25S. The FL intensity of the doped blends was enhanced as the amount of Mn increased in the nanofiller. All samples emitted three violets and two blues colours.
